Just thought I'd say thanks for this post. It's amazing how open people are happy to be, and quite a relief too! I had the same issue last weekend but just ignored it and prayed I was okay seeing as there's no possibility it could have been a tampon or miscarriage as has been mentioned. I also had the symptom of the most severe cramping I've ever had in my life and have now put it down to the fact that I went on Norethisterone to delay my period for over a week whilst on holiday so I must assume it was just coz it built up for so long.
